Shampoo and I'm not talking about the movie

OK seems to me that all the shampoo's out there now have to have some kind of combination of this and that. Then they have silly little slogans on them. You know what I don't care if there is a cute slogan on the bottle or what mixtures are in it, I just need something that deep cleans. My hair gets oily and I need something that will clean it well when I wash it. OK that inexpensive stuff that says for "Men" dose not work well for me. I don't care if my hair smells like strawberry's or vanilla, I just want it to be clean.
